Title: Key distributing system of ciphering device
Inventor: YAMAMOTO TOSHIYUKI
IPC: H04L9/08
Filed: 1983-06-29
Abstract: PURPOSE:To simplify the key distributing means by generating a key in common for all stations and distributing the key by means of a PKDS system between ciphering devices between a master station and a slave station so as to eliminate the need for management of the key. CONSTITUTION:An open key X from a ciphering device 2 at the master station is transmitted in the form of a secret key alpha and an open key Y from a ciphering device 7 at the slave station are distributed in the form of a secret key beta respectively. The ciphering device 2 makes arithmetic operation from the received open key Y and secret key alpha and the ciphering device 7 makes arithmetic operation from the open key X and secret key beta respectively and they produce a key K in common to both. The ciphering device 2 of the master station ciphers the key K by using a common ciphering key K-1 having been used before the exchange of key to remaining slave station ciphering devices 8, 9 so as to produce a key Ek-1(k), which is distributed to the ciphering devices 8, 9 of the slave station from the ciphering device 2 of the master station. Thus, the ciphering device 2 of the master station side and the ciphering devices 7-9 of the slave station side obtain the common diphering key K.
